Also known as: C2ta; Mhc2ta
Summary: Predicted to enable DNA-binding transcription factor binding activity and transcription cis-regulatory region binding activity. Involved in several processes, including cellular response to electrical stimulus; cellular response to exogenous dsRNA; and regulation of transcription by RNA polymerase II. Located in cell surface. Used to study periapical periodontitis. Human ortholog(s) of this gene implicated in Addison's disease; MHC class II deficiency; autoimmune disease (multiple); and myocardial infarction. Orthologous to human CIITA (class II major histocompatibility complex transactivator). [provided by Alliance of Genome Resources, Dec 2024]
Expression: Biased expression in Spleen (RPKM 130.5), Thymus (RPKM 59.8) and 6 other tissues See more

Study found that natural allelic differences in the Mhc2ta gene regulating MHCII expression levels impact microglial phenotype, antigen presentation capacity and dopaminergic pathology after overexpression of human alpha-syn. These results indicate that Mhc2ta is a key upstream regulator of the inflammatory response in Parkinson's Disease pathology.
Title: Allelic difference in Mhc2ta confers altered microglial activation and susceptibility to α-synuclein-induced dopaminergic neurodegeneration.
Naturally occurring allelic variability in Mhc2ta profoundly affects the quantity of class II histocompatibility gene expression in the central nervous system and modulates susceptibility to autoimmune neuroinflammation.
Title: Vra4 congenic rats with allelic differences in the class II transactivator gene display altered susceptibility to experimental autoimmune encephalomyelitis.
Silencing of CIITA transcription is recessive in trophoblasts and involves an epigenetic mechanism other than promoter methylation. Trophoblasts may be missing a factor that regulates chromatin structure at the CIITA promoter.
Title: Class II transactivator (CIITA) promoter methylation does not correlate with silencing of CIITA transcription in trophoblasts.

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
